[Scip] SCIPaddColDive()

[Jonas Witt]

Hi all,

the problem with the SCIPaddColDive() is that SCIP is not able to create 
a lp column without a corresponding variable. So it is possible to add 
an existing column of a variable to the dive lp, but if you want to 
create your own column (this is what I wanted to do) this is a bit more 
difficult.

One might write functions to create an empty column, to add a column to 
a row or to delete a column. In the SCIPlpShrinkCols() there are some 
assertions that would not fit anymore, if a column has no corresponding 
variable (assert(col->var) != NULL etc.).

Do you have any ideas how to make this work?

Best regards,
Jonas
